Class BikeAlgorithm

java.lang.Object

zeroecho.core.CryptoAlgorithm

zeroecho.core.alg.AbstractCryptoAlgorithm

zeroecho.core.alg.bike.BikeAlgorithm

public final class BikeAlgorithm
extends AbstractCryptoAlgorithm

Integration of BIKE (Bit Flipping Key Encapsulation) algorithm

Declares BIKE as a AbstractCryptoAlgorithm and registers its supported roles, contexts, and key builders within the ZeroEcho framework.

Capabilities

• KEM - encapsulation and decapsulation of shared secrets using public and private keys.
• Agreement - initiator and responder flows for MessageAgreementContext built on top of BIKE KEM.
• Asymmetric key builders - generation and import of BIKE keys from BikeKeyGenSpec, BikePublicKeySpec, and BikePrivateKeySpec.

Provider

Uses the BouncyCastle Post-Quantum provider (BCPQC). The provider must be registered in the JCA Security before use.

Example

BikeAlgorithm bike = new BikeAlgorithm();

// Generate a key pair
KeyPair kp = bike.asymmetricKeyPairGenerator(BikeKeyGenSpec.class)
                 .generateKeyPair(BikeKeyGenSpec.bike256());

// Encapsulation using recipient's public key
KemContext kemEnc = bike.createContext(KeyUsage.ENCAPSULATE, kp.getPublic(), VoidSpec.INSTANCE);

// Decapsulation using private key
KemContext kemDec = bike.createContext(KeyUsage.DECAPSULATE, kp.getPrivate(), VoidSpec.INSTANCE);

Constructor Details

BikeAlgorithm

public BikeAlgorithm()

Constructs and registers the BIKE algorithm with all its roles and key builders.

Registers:

• KEM (encapsulate/decapsulate)
• Agreement (initiator/responder)
• Asymmetric key builders for BIKE key specifications

Method Details

parameterSets

public List<ParameterSetDescriptor<? extends AlgorithmKeySpec>> parameterSets()

Description copied from class: CryptoAlgorithm

Returns the discoverable parameter sets (or parameterized templates) supported by this algorithm.

Callers (UIs, provisioning tools, policy engines) use this list to present users with valid, named key-generation options without prior knowledge of the concrete algorithm. Each entry is either a pre-built ParameterSetDescriptor.Concrete (ready spec) or a ParameterSetDescriptor.Template (user-supplied arguments produce the spec).

The default implementation returns an empty list. Algorithms with finite, enumerable parameter sets should override this method. Overrides must return immutable lists in stable order, with unique nonblank descriptor identifiers. Registry loading validates a snapshot; external providers remain responsible for maintaining the contract on subsequent calls. Implementations may use ParameterSetDescriptor.snapshot(List) to validate and copy their list.

Overrides:

Returns:

immutable list of parameter set descriptors; never null
